Can the DN7.8 Quick-Connect Socket with Valve, Hose Tail, Nickel-Plated Brass, Series 25KA handle media other than compressed air, such as aggressive liquids or gases?

Yes — the DN7.8 Quick-Connect Socket with Valve, Hose Tail, Nickel-Plated Brass, Series 25KA is designed to handle media beyond compressed air. The product description states it reliably handles compressed air, liquids, and gases, with high flow rates (1800 l/min at 6 bar for air; 33.5 l/min for water at Δp=1 bar) and a maximum working pressure up to 35 bar. Its construction—nickel-plated brass body, hardened nickel-plated steel sleeve, nickel-plated zinc alloy valve, stainless-steel components, and NBR seals—provides good general corrosion and wear resistance and a temperature range of -20°C to +100°C. Caveats: for aggressive or highly corrosive liquids/gases, compatibility depends on specific chemical compatibility with nickel-plated brass, zinc alloy, stainless steel grade, and NBR seals. Strong acids, bases, chlorinated solvents, ammonia, or certain hydrocarbons may attack plating, base metals or NBR. For aggressive media, confirm chemical compatibility (including temperature and concentration) or consult the manufacturer and consider alternative materials (e.g., specific stainless grades, PTFE seals) to ensure safe, long-term service.
